How to retrieve managed package (conga) via package.xml

bhanukarkra — Tue, 03 Sep 2024 03:40:17 +0000

For managed package we need to append the managed package name as prefix to the component.
For example APXTConga4 is added in front of conga template layout.
If you find the layout name in org, it will be only conga template layout.

        <members>APXTConga4__Conga_Template__c-APXTConga4__Conga Template Layout</members>        
        <name>Layout</name>
    </types>

how to check the schedule class in your org

bhanukarkra — Thu, 15 Feb 2024 09:17:26 +0000

To get the underlying Apex class from the scheduled jobs, the following query can be run.

Query to get the scheduled job underlying apex class.

SELECT ApexClassId,ApexClass.name,Id,JobItemsProcessed,JobType,Status, NumberOfErrors,MethodName, CronTrigger.CronJobDetail.Name FROM AsyncApexJob WHERE JobType ='ScheduledApex'

after running this verify the ids, if your class id is there

Javascript Begineer

bhanukarkra — Tue, 11 Oct 2022 04:29:27 +0000

Javascript: Runs on Javascript Engine
On firefox: Spider monkey
On Chrome: V8

Node: C++ program that include chrome v8 javascript engine, hence Node can be run outside browser and hence makes up Backend.

Ecmascript vs javascript:
Ecmascript is specification and javascript is programing language that runs on echmascript specification.

DataTypes:

Primitive: String, Number, boolean, null, undefined primitives are copied by value
Reference type: Object, array, Function objects are copied by reference

eg:

let x=10;
let y=x;
x=20
console.log(y)//10

but
let x={value:10};
let y=x
x.value=20;
console.log(y)//{20,10}

typeof undefined = undefined
typeof Null= object
typeof NaN=Number

Object: Object property can be changed in two ways

Dot notation
Array bracket

eg: 1

let person={
name:'john',
age:30
};

person.name='Seema';//dot notation
person['name']='Seema';//array bracket. This gets used in case of dynamic value

Array: technically Array is an object, hence typeof Array=object

function: Parameter is at the time of function declaration
Argument is passed from fucntion call

Operators: arithmatic, Assignment, comparision, logical, bitwise.

Arithmatic: +,-,,/,%,*(exponentiation),++, --

Assignemnt: let x=10;
x=x+5; OR x+=5; are same

lose equality: ==
Strict equality: === (check datatype also)

conditional: Ternary operator

let points=100;
let type=points>110?'gold':'silver';

Logical operator with non boolean values:
false||true=true
false||'abc'=abc
false||1=1

if value is not boolean, js engine make it truthy or falsy value

Falsy values: undefined, null, '', 0, false, NaN
Anthing that is not falsy is truthy

short-circuting: false||1||2= 1

if-else
Switch:

let role='guest'
switch(role){
case 'guest': console.log('Guest User');
break;

case 'moderator': console.log('Moderator user');
break;

default: console.log('default');

Loops: For, while, do-while, for-in, for-of

for-in & for-of are used to access objects/arrays

for-in:
`const person={
name='john';
age=30;
}
for(let key in person)
console.log(key, person[key]);
//name john
// age 30

similarly for array
const colours='red','green','Blue'; for(let index in colours) console.log(index, colours[inded]) //0 red,1 green,2 blue

For-of
for(let color of colours) console.log(color); //red, green, blue
with for-of loop no need to have index as in for-in.
For-of loop cannot iterate over object

Break: this is used to jump out of loop
continue: used to jump to execute loop next iteration.

Function vs method.
If a function is a part of object it is called as method.

Factory function: if function is for producing objects, it is called as factory function

In object if key and value are same, then only key can be written
like radius:radius is same as radius.

constructor function: works same to produce objects, however naming convention is used with capital first letter.
Also object can be initialized with this.

cloning an object:
`
const circle{
radius:1,
draw(){
console.log('draw')
}
};

const another={...circle};//taking each property/method of circle object and assigning to another object.
`

const message='hi'//string primitive
const another=new string('hi')//string object

(...) spread operator vs (...) rest operator
Spread operator: takes each element of array.

rest operator accommodate each parameter of function

Getters: To access properties
Setters: To mutate them

var=function scope
Let, const= block scope

This: this reference to the object that is executing the current function

Check you are on which page from LWC

bhanukarkra — Sun, 18 Sep 2022 12:19:49 +0000

To check if the Lightning component is in Lightning Community Page or in Salesforce Lightning CRM page, we can make use of Site Class‘s method – getSiteType().

this return these values

Create an @AuraEnabled method in Apex Controller:

@AuraEnabled
public static String getSiteType() {
    return Site.getSiteType();

controller to fetch

var communityPageKeys = ['ChatterNetwork', 'ChatterNetworkPicasso'];
var action = component.get("c.getSiteType");

action.setCallback(this, function (response) {
    if (response.getState() === "SUCCESS") {
        if (communityPageKeys.indexOf(response.getReturnValue()) < 0) {
            // This is not a community page
        } else {
            // This is a community page
        }
    }
});

$A.enqueueAction(action);

How to use Hyperlink of image in formula field

bhanukarkra — Fri, 01 Jul 2022 14:24:04 +0000

Make an image clickable and navigate to any page in salesforce.
Use hyperlink function with Image function as below:

If statement to make the formula field empty if value is coming empty

IF( NOT(ISBLANK(PublicUrlText__c) ) , HYPERLINK("https://emaarservice--mysterysho--c.documentforce.com/sfc/dist/version/renditionDownload?rendition=THUMB720BY480&" + PublicUrlText__c, IMAGE("https://emaarservice--mysterysho--c.documentforce.com/sfc/dist/version/renditionDownload?rendition=THUMB720BY480&" + PublicUrlText__c, "No Image", 200,200)),"" )

How to navigate to a page in LWC after button click/record creation

bhanukarkra — Tue, 28 Jun 2022 04:02:30 +0000

use navigation mixing

1)Add library

import { NavigationMixin } from 'lightning/navigation';

2)add navigation mixing in default class

export default class ObservationCreationPage extends NavigationMixin(LightningElement) {

3)add navigation mixing in function


handleSuccess(event) {
        this.loaded = true;
        this.closeQuickAction()
Successfully!! ${event.detail.id}`, "success")
        console.log("handle Success",JSON.stringify(event.detail))
        this.showToast("Success!!", `Observation Created Successfully!!   Obs No.: ${event.detail.fields.Name.value}`, "success")
        this[NavigationMixin.Navigate]({
            type: 'standard__recordPage',
            attributes: {

CI/CD Tools -Continuous integration/continuous delivery (CI/CD). like Netflix. As the data get deployed immediately.

Salesforce DX - Salesforce Developer Experience -Salesforce DX is much more than just a new set of tools and rules. It serves as an alternative to change set development and shifts the source of truth from Org to Version Control System (VCS). It shifts our development focus from org development to package development and more. Make Disposable instance exact copy of sandbox. VSCode is a part of SFDX.

Java JDK - Java Development Kit-
Java JRE - Java RunTime Engine-
The JVM is the Java platform component that executes programs.
The JRE is the on-disk part of Java that creates the JVM.
The JDK allows developers to create Java programs that can be executed and run by the JVM and JRE.

Product Line Manager A product line manager oversees the efforts to increase market share and profitability of products in a company. As a product line manager, you research and study the market to determine fair price points and compare competitor's products.

Cross Product Lead
Product leads are responsible for the development of new products within a particular company. They are key members of cross-functional product development teams that typically include engineers, researchers, technologists, and representatives of marketing, finance, and manufacturing departments.

Product Line Architect Perform design, development and support of existing and new products.
Understand product vision and business needs to define product requirements and product architectural solutions.
Develop architectural and design principles to improve performance, capacity, and scalability of product.
Work with Product Manager in planning and execution of new product releases.

BDD Behavior Driven Development: This means creating an executable specification that fails because the feature doesn't exist, then writing the simplest code that can make the spec pass. You repeat this until a release candidate is ready to ship.

TDD Test Driven Development: This means writing a test that fails because the specified functionality doesn't exist, then writing the simplest code that can make the test pass, then refactoring to remove duplication, etc. You repeat this Red-Green-Refactor loop over and over until you have a complete feature.
The key difference is the scope. TDD is a development practice while BDD is a team methodology. In TDD, the developers write the tests while in BDD the automated specifications are created by users or testers (with developers wiring them to the code under test.) For small, co-located, developer-centric teams, TDD and BDD are effectively the same.

SIT System integration testing (SIT) involves the overall testing of a complete system of many subsystem components or elements. The system under test may be composed of hardware, or software, or hardware with embedded software, or hardware/software with human-in-the-loop testing.

DLR Dynamic Language Runtime: The DLR makes it easier to develop dynamic languages to run on the .NET Framework and to add dynamic features to statically typed languages.

POC Proof of Concept: Showing workable demo to show capability
Regression Testing: Testing whole code based on new code changes

Penetration Testing: To test for security breach

Load testing: To check load or Bulk Data

Aura Components

bhanukarkra — Sun, 20 Jun 2021 06:37:18 +0000

*8 components in Aura Bundle.
*3js, 1css, 1svg, 1 cmp, 1doc,
*TO run Bundle need App

Attributes name="xyz" value =1 replaces variables to show in front end
To show {!v.xyz}
v signify Component (ie; visual value)
c signify controller (ie; Controller value)

For back end use .js controller

aura:attribute can be defined directly in application also because both are front end.
Now we have 2 different ways to to to define aura:attribute

Creating a lightning component and then calling it in the lightning application,
lightning component attribute inside application

Button

Js Controller = all functionality inside this.

implements
: to make your component available for record pages and any other type of page,

Calculator App
Component=AddComponent.cmp

<aura:component >
    <aura:attribute name="num1" type="Integer" default="30"/>
    <aura:attribute name="num2" type="Integer" default="20"/>
    <aura:attribute name="sum" type="Integer" />
      {!v.num1} + {!v.num2} = {!v.sum}
   <br></br>
  <ui:button label= "Press Me" press="{!c.add}"/>
</aura:component>

Js.Controller =AddComponent.js

({
 add : function(component) {
       var xyz = component.get("v.num1") + component.get("v.num2");
        component.set("v.sum",xyz);
                                              }
})

Output:

You can only use {!} Syntax in markup languages like HTML, hence in .app and .cmp we are using {!} for expression.

ifElse

<aura:component>
  <aura:attribute name="edit"
                             type="Boolean"
                             default="True"/>
   <aura:if isTrue="{!v.edit}">
      <ui:button label="submit"/>
       <aura:set attribute="else">
          Hello, Welcome to SalesfrceKid Platform
     </aura:set>
   </aura:if>
</aura:component>

Output

Value Providers

Value providers encapsulate related value together, similar to how an object encapsulates properties and methods.
The value providers for a component are v(view) and c(controller).
A component's view refers to its attribute set.
A component's controller enables you to wire up event handlers and action for the components. It's where you control your component's logic.

Global Value Providers /h5>
Here are some global value providers you need to know :

globalId: It returns the global ID for a component has a unique globalId, which is generated runtime-unique ID of the component instance.
$Browser: It returns information about the hardware and operating system of the browser accessing the application.
$Label: It enables you to access labels stored outside your code.
.
.
.
.
etc

<aura:component>
  Browser running on Tablet: {!$Browser.isTablet}
   <br></br>
    Is it running on IPhone: {!$Browser.isIPhone}
    <br></br>
     Is it running on Android: {!$Browser.isAndroid}
     <br></br>
I am Running on : {!$Browser.FormFactor}
</aura:component>

output
Browser running on Tablet: false
Is it running on IPhone: false
Is it running on Android: false
I am Running on DESKTOP

Server Side Controller or Apex Class

With Sharing: To respect salesforce security to connect with client side controller
Static and stateless methods: Method don't care who is calling them
@AuraEnabled:to enable the client and server-side access to the method.
Example: Apex class (server side component).apxc

public with sharing class simpleController//with sharing to share
{
 @AuraEnabled //to enable access
 public static String serverEcho (String firstName) //static
 {
  return('Hello from the server'+ firstName); 
 }
}

component

<aura:component controller="simpleController"> //linking apex
  <aura:attribute name="firstName" 
                             type="string" 
                             default="salesforceKid"/>
<ui:button label ="callServer" press="{!c.echo}"/> //calling js
</aura:component>

JS controller (client side controller)

//This is not class. It is JSON object with map of name value pair. Having only action handlers.
In function (component, event, and helper—though you can name them differently)
({
 echo : function(cmp, event, helper) { //Action handler as func.
                                       //can have only 3 paramtr 
  var action = cmp.get("c.serverEcho");//linking serverside (ssc) 
                                   controller function serverEcho
        action.setParams({         //Sending parameter to SSC
            firstName : cmp.get("v.firstName")
        })
        action.setCallback(this, function(response){ //callback
            var state = response.getState(); //add to variable
            if(state === "SUCCESS")          //comparing
            {
                alert("This is from server ::"+ response.getReturnValue());      //gets the value returned from 
                                  the server.              
            }
            else if(state === "INCOMPLETE")
            {
                //do something 
            }
            else if(state === "ERROR")
            {
             var error = response.getError();
             if(error)
             {
                 console.log("error"+errors);
             }
            }
        });
          $A.enqueueAction(action);// $A.enqueueAction adds the 
                                 server-side action to the queue.
                                 All actions that are enqueued 
                           will run at the end of the event loop

 }
})

Important:
c. IN component represent client side Component
c. in JS controller represent server side component (apex)
c: is the default namespace. It represents Aura component code you’ve added to your org.

Lightning Application

<aura:application extends="force:slds"> //for SLDS
    <c:serverSide/>
</aura:application>

wrapper Class: Reduce server call and get data at one call

public class wrapperClassController {

 @AuraEnabled 
    public static wrapper method(){
    //Get Required Account And Contact List by SOQL STEP 2
        List<Account> getAccount = [Select Id, Name  FROM Account];
        List<Contact> getContact = [Select Id, Name FROM Contact];    
//Instance before adding a list STEP 3
        wrapper wrp = new wrapper();
        wrp.accList = new List<Account>(getAccount);
        wrp.conList = new List<Contact> (getContact);
        return wrp;
    }

//Main Wrapper Class STEP 1
    public class wrapper{
       @AuraEnabled //Annotation when using for lightning component
          public List<Account> accList;
       @AuraEnabled 
          public List<Contact> conList;
    }   
}

Init
//doInIt Handler To call the c.doInIt action when screen load

//abc is funtion name on CSC.(client side controller)

Events in Aura

component composition

communicate from parent component to child component, we include child component inside the parent component.

Parent To Child

example: parentComponent.cmp

<aura:component>
<aura:attribute name="valueToChild" 
                          value="String">
<h6>This is parent component</h6>
//Including child component in parent 
<c:childComponent value="{v.valueToChild}"/>
</aura:component>

Parent To Child Component Communication :
In parent to child component communication, we can communicate by passing value from parent to child as explained above example.
But when we want to communicate from Child To Parent we cannot directly pass value inside an attribute. In that case, we use lightning Events ⚡️

Event for Child to parent

1)Component Event
2) Application Event

1)Component Event
Component Event On child-->Register it on Childcmp-->fire Event from Child Js-->use parent JS to handle Event--> pass value to parent cmp to use.

lightning Tag vs UI tag
UI tag was initially introduced
lightning tag has inbuilt SLDS we do not need to put extra effort to improve the look and feel, also it has may awesome tags to handle the Error or bad inputs.

VisualForce Basics

bhanukarkra — Wed, 26 May 2021 13:38:27 +0000

{! } - Anything inside this format is used to assign values dynamically

$- Prefix is used to denote global action

& - character is the formula language operator that concatenates strings.

$Resource - For static Resource
URLfor() - For combining zipped static resource

*when the {! contacts } expression is evaluated. On this page, Visualforce translates that expression into a call to your controller’s getContacts() method.
The getContacts() method is called a getter method

Wrapper Class vs Helper Class vs Controller Class

bhanukarkra — Wed, 26 May 2021 03:37:43 +0000

Wrapper Class: To wrap the Data types to make a single object which can be assessable easily in other classes.

Controller Class Controller class contains public methods called Action methods. Each method has a one-to-one link with a possible user action, ranging from the click of a button to another trigger. The controller class methods process input data, execute application logic and determine view.

public class WrapNitesh {

//CONTROLLER CLASS

    public list<wrapaccount> wrapaccountList { get; set; }
    public list<account> selectedAccounts{get;set;}    

      public WrapNitesh (){

     //if(wrapaccountList ==null){
          wrapaccountList =new list<wrapaccount>();
          for(account a:[select id,name,billingcity,phone from account limit 10]){
           wrapaccountlist.add(new wrapaccount(a));

           }
        // }
      }

    //### SELECTED ACCOUNT SHOWN BY THIS METHOD
      public void ProcessSelected(){
     selectedAccounts=new list<account>();

      for(wrapaccount wrapobj:wrapaccountlist){
           if(wrapobj.isSelected==true){
           selectedAccounts.add(wrapobj.accn);
           }

         }
      }

  //##THIS IS WRAPPER CLASS
   // account and checkbox taken in wrapper class

   public class wrapaccount{

    public account accn{get;set;}
    public boolean isSelected{get;set;}

       public wrapaccount(account a){

         accn=a;
         isselected=false;
       }
  }
}

Helper Class helper class is used to assist in providing some functionality, which isn't the main goal of the application or class in which it is used

function linesOf($mls) {
    return preg_split('/\s*\n\s*/',trim($mls));
}
